This is a simple browser-based tool that converts QR codes into 3D-printable STL files.
It uses three.js to render the model and exports clean geometry you can slice and print.

• Input custom data to encode as a QR code (e.g. URLs, text, etc.)
• Choose error correction level: L (7%), M (15%), Q (25%), H (30%)
• Optionally select QR version (size) from 1–10 or let it auto-size
• Set real-world dimensions:
  • Units: millimeters / centimeters / inches
  • Width/height of the QR plate
  • Extrusion depth (thickness)
• Optional flat base under the QR code
  • You can set its width and depth
• Interactive 3D preview with rotation and zoom
• Download clean ASCII STL files
  • Filenames include dimensions and units for easy tracking

• Vanilla JS + ES Modules
• three.js (via CDN import map)
• qrcode-generator
• No bundler, framework, or install needed — runs 100% client-side

• Supports QR version 1–10 (the full spec goes up to 40)
• Long or complex text may exceed the selected version
  • You’ll get a helpful popup if this happens
